TECHNICAL FIELD

The present disclosure relates to the technical field of a fiber opticlink device, and especially to a fiber optic adapter.

BACKGROUND

A fiber optic adapter is widely used in the field of a fiber optic linkdevice, and fiber optic connectors with different interface types may beinserted into two ends of the fiber optic adapter, to realize theconversion between different interfaces such as FC, SC, ST, LC, MTRJ,MPO and E2000. In order to facilitate the connection of the connectorsat the two ends, the fiber optic adapter is connected with the fiberoptic connector through a port. A sleeve is arranged between thecorresponding ports. The fiber optic connectors located at the two endsof the fiber optic adapter are respectively inserted into thecorresponding ports. Optical fibers at heads of the fiber opticconnectors are respectively inserted into two ends of the sleeve, andaligned through the sleeve, to avoid the misalignment of the opticalfibers and reduce the loss.

The existing fiber optic adapter usually adopts an elastic tab torealize the opening and closing of an individual cover plate (namely thelight shielding plate) and an individual channel (namely the ports),therefore, the assembly of the elastic tabs (namely the elastic member)of the fiber optic adapter is relatively cumbersome, thereby leading toa low production efficiency. In addition, the existing fiber opticadapter adopts one elastic tab to realize the mutual opening and closingof two cover plates and two channels, which cannot achieve individualopening and closing, thus the application effect is poor.

Therefore, there is an urgent need to provide a new type of fiber opticadapter to solve the above problems.

DETAILED DESCRIPTION

Hereinafter the technical solution of the present disclosure will befurther described in conjunction with accompanying drawings andembodiments.

FIG. 1 is a structural schematic diagram illustrating a fiber opticadapter provided by the present disclosure. The fiber optic adapterincludes at least two ports 11 for connecting to fiber optic connectors(not shown in the drawings). In one example, an even number of ports 11are provided, for example, the even number may be 2, 4, 6 and the like.Each of the ports 11 is provided with a light shielding plate 12. Anelastic member 13 is shared between every two adjacent light shieldingplates 12, and configured to support the two adjacent light shieldingplates 12 to shield the corresponding ports 11 thereof, namely enablethe light shielding plate 12 to independently open or close. In thepresent disclosure, by sharing the elastic member 13, which isconfigured to support the every two adjacent light shielding plates 12to shield the corresponding ports 11, between the every two adjacentlight shielding plates 12, each of the light shielding plates 12 of theports 11 of the adapter can be independently opened or closed. And theelastic member 13 is shared between the two light shielding plates 12,so that the assembly efficiency is improved, thereby solving the problemthat the assembly of the elastic tab of the existing fiber optic adapteris relatively cumbersome.

In one embodiment, the fiber optic adapter further includes a main bodyportion 1 and a lid body 2 clamped to the main body portion 1. Aplurality of ports 11 are formed by clamping the lid body 2 to the mainbody portion 1. In one embodiment, the main body portion 1 is providedwith a rotating shaft (not shown in the drawings). Each of the lightshielding plates 12 may be rotatably arranged at a respective port 11 ofthe main body portion 1 through the rotating shaft. It should beunderstood that, based on the considerations of ease of installation, aplurality of elastic members 13 may be preferably sleeved on therotating shaft, thereby realizing the assembly of the plurality of lightshielding plates 12 and the plurality of elastic members 13.

FIG. 2 is an exploded schematic diagram of FIG. 1. In one embodiment,each of elastic members 13 is integrally formed and arranged on an innerside of the every two adjacent light shielding plates 12, therebyrealizing the support of the elastic members 13 to the light shieldingplates 12. It should be understood that the elastic members 13 only needto realize the supporting effect for the light shielding plates 12. Inone example, a supporting portion of an elastic member 13 is embedded inthe interior of a respective light shielding plate 12. In anotherexample, the supporting portion is integrally formed with the respectivelight shielding plate 12 during the machining. In still another example,the light shielding plate 12 may be provided with a groove or the likecapable of accommodating the supporting portion.

In one embodiment, each of the elastic members 13 includes a firstsupporting arm 131, a second supporting arm 132 and a spring 133. Thefirst supporting arm 131 is abutted against the inner side of one of thetwo adjacent light shielding plates 12, and the second supporting arm132 is abutted against the inner side of another of the two adjacentlight shielding plates 12. The spring 133 is connected to the firstsupporting arm 131 and the second supporting arm 132 respectively, andarranged at a bottom between the every two adjacent light shieldingplates 12. It should be understood that the first supporting arm 131 andthe second supporting arm 132 are the aforementioned supportingportions.

In one embodiment, each of the light shielding plates 12 is providedwith an avoiding groove 121 for avoiding an optical fiber at the end ofthe fiber optic connector, which can prevent the optical fiber at theend of the fiber optic connector from being damaged when the fiber opticconnector is inserted.

In one embodiment, a manner for conveniently fixing the first supportingarm 131 and the second supporting arm 132 may be as follows. A limitingblock 122 is arranged on the inner side of the each of the lightshielding plates 12. A space for accommodating the first supporting arm131 and the second supporting arm 132 is formed at a position of thelimiting block 122 opposite to the avoiding groove 121.
